本文通过对１９３例高血压病患者住院病历的分析，发现（１）左室心肌质量指数高于正常者（男＞１３４ｇ／ｍ２、女＞１１０ｇ／ｍ２）共９０例，其心电图左室肥厚的敏感度为１８．９％，特异度９３．３％。当左室心肌质量指数男＞１７４ｇ／ｍ２、女＞１５０ｇ／ｍ２时，心电图左室肥厚的敏感度最高，为３３．３３％，特异度９０．９％。但心电图左室肥厚的敏感度并非随左室心肌质量指数增加而增加。（２）心电图左室肥厚组与正常组比较其左室心肌质量指数有显著差异，Ｐ＜０．０１。肥厚组与高电压组的心肌质量指数比较Ｐ＞０．０５。（３）年龄、性别对心电图左室肥厚的敏感度无影响。
In this paper, 193 cases of hypertension inpatient medical records were analyzed and found that (1) left ventricular mass index higher than normal (male> 134g / m2, women> 110g / m2) a total of 90 patients with ECG of left ventricular hypertrophy Sensitivity 18.9%, specificity 93.3%. When left ventricular mass index of men 174g / m2, women> 150g / m2, the sensitivity of left ventricular hypertrophy was the highest, 33.33%, specificity 90.9%. However, the sensitivity of ECG left ventricular hypertrophy is not increased with the increase of left ventricular mass index. (2) There was a significant difference in left ventricular mass index between left ventricular hypertrophy group and normal group (P <0.01). Comparison of myocardial mass index between hypertrophic group and high-voltage group P> 0.05. (3) Age and gender had no effect on the ECG sensitivity of left ventricular hypertrophy.
